To all whom t may concern: i

Be it known that I, HERBERT FOX, a subliect of the King of Great Britain, and resident of the city of Hamilton, county of lVentworth, Province of Ontario, in the Dominionof Canada, have invented certain new and useful Improvements/[in Gra-in Shockers, described in the following specification and illustrated in the accompanying drawings,

l0 that form part of the same.

The objects of the invention are to facilitate the work of harvesting grain, enabling crops to `be garnered in shorter time and at less expense and to devise a shocker of extremely light but durable constructionwhich mayl be manufactured at a cost which will permit of universal use. y

A still further object is to devise a machine which maybe readily handled with the ordinary horse or tractor power required in operating binders and further, to devise a construction of machine which is light and iexible and will not hamper the operation of the binder.

2.5 The principal features of the invention consist in the novel `construction and arrangement or' parts whereby the sheaves are taken from the binder deck and turned butt downward and deposited on al reciving 3 member by a-swinginggripper member and said sheaves are uniformly packed into ai bundle or shock by horizontally operating packer members and when the bulk of the shock reaches the desired dimensions, the receiving member operates to deposit the shock butts down upon the ground in a compact bundle which will stand effectively.

In the drawings Figure l is a perspective view of a shocker from the Jfront and outer Side `with the sheaf gripper in positionto receive the sheaves from the binder. Fig. 1a is a planet the steering wheel. A

Figure 2 is an enlarged plan view of the parts substantially in the position shown in l-"igure l.

Figure 6 is an elevational view fromthe outside of the machine showing the parts in the position substantiallyy as shown in Figure 5. i

Figure 7 is a side elevational view from 60 the outer side showing the parts-1 in the postion of delivering thesheafi v v- Figure` 8 is an enlarged perspective detail oi the sheaf gripper latch and trip mechamsm. r Y y Figure l9 is anfunderside plan detail of the mechanism for operating the sheaf pack-h er arms inthe inoperative position. Figure l() is a viewsimilar to Fig. 9 show- Figure 11 is an enlarged perspectivei detail of the latch for holdingthe gearshift device. y y, y f y r The main frame ofthe shocker isformed of a pair of angle bars l securedtogether at 7,5.

one end and arranged at an acute angle, the other end being connected to bracket` members 2 in which are'supported the axle' members 3 andV 4 upon which are mounted the' wheels 5 and 6 respectively. Across bar 7 90 is rigidly connected with the bars 1 forward of the wheels, thusforming a rigid frame. A bar 8 is rigidly secured to the angle bars 1 ad]l acent to the forward end and extends to the inward side of the frame, that is, toward the binder. This bar is braced by Va brace rod 9 and the outer end is pivotally connected to a strut extension 10 from the bindf` er'which is not herein shown.` The frame yis drawn along lwith the binder by means of this connection.

Y The. inside axle member 3k extendswell beyond the hub of the wheel 5 and atrussed bar 11 (see Fig. la) is pivotally mounted thereon. One end of thetrussedbar extends downwardly and is twisted to 'form a spade which is adapted to dig into the ground `under certain conditions. The otherend extends over the upper side ofi the wheel and to it is pivotally connected theztie bar 1K2 190 with the gear 23.

which is connected to the rear of the binder frame. The axles 3 and. 4 are bent upwardly and the vertical portions pivot inthe brackets 2 which are notched in the under side to rest on the shouldered portions of the axles holding them in position to hold the wheels straight. The upper end Vof the trussedbar 11 normally extends to the forward side of the inside wheel. A rod 12, Figs. 2 and 5 connects the inside and outside axles so that they'will pivot in unison;` In

the event of the binder backing up the spade end of the bar 11 digs into the ground and throws the upper endconnected .to the tie bar 12 to the rear of the pivot of the wheel, and

the wheels then'follow the backward movei ment of the binderfreely. The shocker thus follows automatically the movements of the binder.

An arm 13 is supported at the inward or binder side of the frame and is' formed with an angled upper end 14 which supports a pair of journal-s 15.1 A corresponding journal 16 is secured to the upper end of the tractionbar 8 and in these journals is mounted a'shaft 17. Upon each end and in the `centre of the shaft '17 are securedthe ellipticaly shaped sheaf carriers 182 which are adapted to receive the sheaves delivered shaft supporting said carriers i-s'constantly rotated so that the carriers turn toward the shocker frame, the sheaves are passed outwardly. v l

The triangular shapedframe is divided centrally by a longitudinal: bar 19'which' extends from theapex of the 'angle bars 1 to the rigid cross bar 7, Figs. 4.2 and -5.

The mainf'd'riving shaft ,20, of the shocker" machine-'is supported inbearings carri-ed by the 'Centre' bar 19V and inner vbar 1 and it-V is connected by a toggle 'joint 21 and shaft 22 with the mechanism of the binder. Y

A bevel gear 23 is mounted on the shaft 20'and a yoke 24 supported on said shaft 2O vis formed with a studprojcction upon which is mounted a bevel gear25y meshing A sprocket wheel 26 forms part of the gear 25 and is connected by a chain 27 to asprocket wheelon the shaft 17 so that the elliptical sheaf carriers operate constantly during the movement of the'binder. The arm 13 supporting the shaft 17 is formed Awith a sleeve end 13T which fits overl the stud projection of the yoke 24, consequently7 the sprockets; will be always maintained in alignment. Shields 2 8 in the form of sheet metal'memb'ers are rigidly `Isupported above the shaft 17 between 'the' elliptical sheaf vcarriers toVAK 'preventlloose straw 'from' fouling between 'said carriers.

` A'tubularbar 29 isurotatably supported iny bearinglbrackets secured'to the. main frame of the machine about opposite the towards the binder parallel with the lower portion forming a bail. Pivotally suspended upon the upper end 30 of the bar 29 is a V-shapedbracket 31 and to the upper ends of this bracket are secured a pair of bars. 32 which extend upwardly and converge towards each other, being connected together at the top and between the upper ends of these bars is piv-otally secured the upper end of a tie bar 33, the lower end of which is pivoted to the front end of the main frame. l

A bar 34 is rigidly secured to the bracket 31 and extends forwardly and rearwardly of the supportingmember 30, the rear end being rigidly connected with the bars 32 l curved so thatthe free ends of each set curve toward the other.

A latclrkeeper 38 is rigidly connected with thebar 30 and extends upwardly therefrom at right-angles having agrearw'ardly and koutwardly curvedl spur 39. A trip shaft 40' arranged parallel with'the sleeve 31 and supportedin lugs projecting therefrom is provided withapivotal latch arm 41 at the inner endwhich extends upwardly and engages the keeper 38.A A link 42 pivotally connected to the latch arm 41 is provided' with an eye '43*which slidably encircles the middle finger of the upper v gripper member 36 and holds it in the raised position shown in Figures land V4 with the latch armfengagingthe keeper'38.

A coiled tension'spring 44 connected at one end to the uprightportion o-f the bail member 29 is'connected at its other end to `an arm 45 secured to the upper gripper 36 and exerts a constant pull to swing the gripper downwardly but it cannot do so while the latch arm 41 is in engagement with the keeper. Tothe centra-1 finger of the llower gripperniember 37 isv pivotally connected a rod 46.which slidably extends Vwhich isfpivotally:supportedffrom the bail `30andV is 'provided with a spur endfO which engages the latch arm 41- and pushes itA out of engagement with the keeper 38.L

The pull of the tension spring 44: then snaps the upper gripper against the sheaf so that it is gripped securely` between the two gripper members.

The main drive shaft 20 supports a crank disc 51 which is operated by a clutch continuously operated by the chain 5l and controlled by'a clutch dog 52. A bar 53 extends vertically between the upper and lower hori zontal portions of the bail 30 `and is arranged substantially Ain the same plane as the crank disc 51. A connecting rod 5d connects the crank arm 55 with a curved extension 56 of the bar 53 so that upon the rotation ofthe crank disc the connecting. rod swings the bail rearwardly on its pivot, which is the tu'- bular bar 29. As the bail swings rearwardly the sleeve 3l is rotated upon the upper end 30 through the connection ofthe tie bar 33 to the outer ends `of the bars 32 thereby swinging the sleeve and the gripper members carried thereby from the substantially horizontal position shown in Figure 3 to the Substantially vertical position shown in Figure 6. This action follows immediately upon the release of the latch arm d1 from the keeper 38, said latch arm rotating the trip shaft Ll0 immediately upon the release of the latch from engagement with the keeper.

The trip shaft l0 is provided with a cranked end 57 which is` connected by a rod 58 to a pivotal arm 59 which normally engages the clutch dog holding it out of gear but which ,upon the tripping of the latch the arm 59 releases the clutch dog causing the clutch to operate thel crank disc to swing the bail rearwardly.

It will be noted that the head of the sheaf is not brought into contact with any portion of the mechanism. As the body of the sheaf is gripped by the gripping members it is turned from the horizontal to a vertical position and it is ready to be delivered to the shock forming mechanism.

Bracket members 60 are secured to and extend downwardly from the rigid crossbar 7 of the l.frame and to each of these is pivotally secured an arm 6l to which `is connected the tubular cross bar 62 which forms vthe support for the skid bars 63 which receive the butt ends of the sheaves. llhese skid bars are connected to the tubular crofis'bar and extend forwardly, the front ends being converged and rigidly secured together in two sets the foremost ends being supported by the swinging links 64: supported from the main frame. The tubularl cross bar is normally supported in a raised position as Iillustrated in Figures 3 and 6 by a mechanism which will be hereinafter explained.

The axle members 3 and 4g supporting the wheels extend vertically through the bracket members 2 and project lupwardly a considerable height, being supported mid-way of their height by sleeve brackets carried by the bent bars 65 secured to the lateral ends of the cross bar 7.

A bail shaped tubular bar 66 is supported Y in bearings carried bythe upright ends of the axle members 3 and 4t, the central bent portion extending rearwardly and forming the upper back portion of the sheaf receptacle. A plurality of rods 67 are'secured in the bail and extend angularly downward therefrom to support the sheaves.

A pair of U-shaped frame 68 are pivotally supported one upon each of the vertical aXle members so that the end portions 69 may swing inward. Pivotally connected to the upper and lower portions 69 of the U-fralnes are the hook-shaped bars 70. These are connected by vertical spacers 71 and interu'mediately arranged hook-shaped bars 7 2 are secured tothe spacers and the outer ends are bent downwardly and secured to the lower hook bars. These sets of hook bars are arranged each side of the machine and they are adapted to be operated to move forwardly and to swing inwardly` and pull the sheaf fromy the gripper when said gripper is inthe rearward position as illustrated in Figure 6. The hook members then carry the sheaf rearwardlyy with the butt engaging t-he skid bars. thus form the sheaf packers.

The means for operating the sheaf packers consists primarily ofcrank arms 7 3 mounted on vertically disposed axes'arranged toward the sides of the frame. A shaft 74C is supported` parallel with the cross bar 7 and to These members f the rear thereof in bearings 75 arranged beneath the main frame as shown in `Figures 9-and l0, and this shaft is constantly rotated by a sprocket chain connection 76 with the main drive shaft 20. Slidably arranged upon and near the ends of the shaft 74 are the bracket members 77 which carry vertical studs on which are rotatably mounted the bevel gears 7 8 to which the crank arms 7 3 are connected. Bevel pinions 79 are rigidly secured upon the shaft 74 near each end and are adapted to mesh with the gears 7S when said gears are moved into contact therewith by the sliding of the bracket members 77.

, rlhe sheaf packers are operated alternately and it is desired that when either one of said backers is o ieratino' the other will beV 8() which is formed with a recess 81, which when the gearisvin the outward position as illustrated in the left hand side of Figure 9, receives the end o f a rigid strut 82 and thus locks the gear securely from rotation. On the upper side each gear is provided witha lug projection 83.

Pivotally mounted upon the cross bar 7 is a bent bar 84, the ends of which are adapted toengage the lug projections of the bevel gears 78, said bar being so arranged Y that when one end thereof engages the lug projection of one gear to prevent the gear from being shifted inwardly to mesh with its pinion, the other end will be free of the lug on the other gear thus allowing it to be moved inwardly into mesh with its operating pinion. The swinging of the bar 84 reverses the conditions. l

A member 85 is secured to the bai' 84 and is notched to engage a pin on the swinging latch 84 carried on the bar 7 to hold the bar 84 in either Vone of its adjusted posit-ions. Y

The position of the bent bar 84 isregulated by the lug projections 83 for when one end of the said bar isso arrangedv as to obstruct the lateral movement of one of the gears, the other end will overlap the path of movement of the lug of the other gear so that as the unobstructed gear rotates the lug will strike the bent bar and swing it on its pivot to clear the other gear before the operating gear moves out of mesh and instantly as the operating gear moves out of mesh the lug thereon movesy into line with the obstructing bar.

The sliding bracket members 77 carrying the gears 78 are connected by link rods`86 to a yoke 87 carried on a centraly floating rod 88, said rod extending through said yoke and having a compression spring at either side which permits the'bar to move even though the operation of the gears Y is not completed thus allowing for variation in timing the operation of the various co-acting parts and rendering absolute-accuracy unnecessary. Y

A bell crank lever89 is pivotally mounted upon the tubular bar 29 between the bar 53 and the longitudinal centre b-ar of the frame. The upper end of this lever is connected by a rod 90 to the crank arm 55, which rod swings the lever on its pivot with the operation of the crank. The fioating rod 88 is connected to the lower end of the lever 89 below its pivot so that'as the upper end is swung backwardly the rod 88 is pulled forward thus pulling upon the yoke 87 and the link rods 86. This pull draws upon the slidable brackets 77 carrying the bevel gears 78 but as the bar 84 engages either one of the gears to prevent its lateral movement on the shaft 74 the other one will be operated and drawn into mesh with it-s correspond-ing pinion on the shaft and as said shaft 1 is continuously operating the bevel gear 78 brought Vinto mesh with the pinion immediately commences to rotate and the crank arm 73 carried thereby moves therelative packer outwardly and forwardly This action occurs simultaneously with `the backward movement ofthe sheaf carrying bail and the hooked ends of the packer are moved well forward of the ends of the sheaf gripper by the time said gripper is turned to the position illustrated in Figures 5 and 6. The rotation of the gear continuing swings the packer inwardly so that the hooked ends pass in front of the sheaf and the further continued movement pulls the sheaf from the grippeigcarrying it backwardly' on to theskids.

It isv necessary to delay the'operation of the sheaf gripper when it reaches its backward position and this is accomplished by arranging an arm 91 held in the path of the clutch dog 52 which releasesthe clutch and stops the movement of the cra-nk arm ywhen it is moved to its full rearward position. The arm 91 is held up to the clutch by'a rod 92 connected to a. cranked bar 93 eX- tending across the frame above the cross bar 7. This cranked bar is formed with the crank portions 94 extending over the gears 78 into the path ofinovement of the' lug projections 83 on the bevel gearsk 78 and the bar is held toward the gears by the spring .93 Fig. 2. l/Vlieneither one of the gears has rotated to move the packer to strip the sheaf from the gripper the lug proj ection on the gear engages the bevelled portion of thecrankedbar and swings it for` wardly on its pivot, pushing upon the'rod 92 to throw the arm 91 clearof the clutch dog, thus causing the crank arm 55 to continue its operation andfswingl the bail cariyingthe sheaf gripper back to itsv forward position.

It will be noted that when the sheaf gripper is in the full forward position it is offset to the inward side of the machine, that is, closefinto the elliptical sheaf carriers but as the bail is swung backward the relation between the bail and the gripper carrying bar 34' alters and the rod 46 connected to the lower member 37 engages the eye 47 on the bail and pulls said lower member outwardly. The tension ofthe spring 44 causes the member 36 to 'follow the member 37 so that when the gripper 'has reached its farthest position backward it will be in centralalignment with the frame as shown in Figure 5, placing the .sheaves centrally for either packer.

The shock bail 66 pivotally supported from the vertical axle members forms a pocket to receive the sheaves and as these are deposited successively the pressure swings the bail upward on its pivot. Near Yeach end of the rbail 66 is connected a crank arm 95 and onV the outer end of each of these crank arms, which extend upwardly, is a link 96 which engages a lug on the crank arm below the link, said link being normally held in a substantially right aiigulaiposition withthe crank. Rods 97 extend downwardly from the ends of the links 96 and the `lower ends slide in sleeve members` 98 pivot-ally secured to the rearwardly extending portions v99 of the pivotal arms 61 supporting the tubular cross bar- 62 which carries the skids. To the lower' end of the outer rod 97 is pivotally secured the rod 100 which extends forwardly -and is connected to the cranked end 101 of a rod 102 which is pivotally supported transversely ot' the frame forwardly or the crossv bar 7. The inner end of the rod 102 is provided with a crank end 103 lwhich eX- tends forwardly and is pivotally connected to a U-sliaped yoke 104. A rod v105 is pivotally connected to the llower-end of the lever 89 and slides loosely through a hole in the forwardend of the U-shaped yoke 104. A sleeve 106 encircles the rod105 rearwardly of the yoke end and said sleeve is of shorter lengththan the distance be! tween the yoke ends. The rear end of the rod 105 is provided with a stop lug 107 which is adapted to engage the end ot' the sleeve 106. Y l A pair of links arepivoted to the rear end of the yoke 104and are connected at their other` endstoa crossbolt in the rigid brackets Y supported on th'ebar 19. An elbow-shaped link 108 is also" pivotally -eonnected to t-he rear endet' the yoke 104'and extends over the pivot bolt of the links and thus forms a lock joint.` An velbowed bar 109 is pivotally secured to the rear end ot link 108 and is rigidly secured to the skid bar 62. A sheet metal guardZ is secured to the bar 109 and covers the gear mechanism for operating the packers but when the bar 109 is moved backwardly and the skids are dropped it assists in clearing the butts of the grain from tlie-transiferse parts of the structure.- l I As the sheaves are packed npoii the skids and their bulk increases the bail swings upward and Ythe crank arms swing rforwardly, pushing downwardly upon the rods 97 against coil f compression springs 110. The lock joint formed by links @o and 108 is not disturbed unt-il the bail reaches aL predetermined position accordiiig `to the bulk ot the shock, when the rod 97 pulling upon the rod rotates the crank-'edv rody 102 to swing the yoke member 104 so that the rear lug end thereof will move up against the rod and as the rod 105 moves forwardly by the swinging of the bell crank level 89, the rear end offsaidv yokefmoves behind the end of the-rod, then as the rod moves backwardly `it pushes on the yoke and pushes the link 108 upwardly causing the link 108 and yoke 104 to bend on their connecting pivot breaking the lock joint formed by said members and the bar 109 swings downwardly on the arcor the pivot of the arms 61 to the positionshowii in Figure 7. The skids are thus dropped close to the ground and the butt ends olL the sheaves carried thereon will be engaged ranged brackets '10n the ends of the skid bars. The downward movement of the'arms 61 pulls upon therods 97 .thereby throwing the bail `iipwardly to the position shown in'Figure 7 so that it clears the heads` of the sheaves. i i

In order to hold the shock `from shaking apart as it is discharged,- iiiwardly sloping side rods 111 are pivoted in `brackets112 supported yfrom the rigid side bars 65 `connected with kthe ends of the cross bar 7. The side arms 111 are spring held inwardlyr against the sheaves by coil springs 113'. 'In order to support the-forward sheaves of the shock against dislodgem'ent from the bundle during the discharge, I provide ja pair of arms 114 which are vadapted to swing horizontally to follow the sheaves oil? the skids.` These arejournalled in vertically arthe bars 65 and are offset adjacent tol their'cra'nked ends andare encircled at the offset' by the' eye. ends of the rods 116, theupperendjs of which are connected to theouter ends of the links 9 6. These rods being connected to the' links 96 provide certain yflekibilityzof action as against the Adownward movement yof the rods 97 and'prevent too positive a sweep,- ing action als the sheaves are discharged. 4.ln operating this machine, it is coupled to' the discharge side of the binder in the man-l ner described and' as the sheaves are de-l4 livered :trom the binder deck they fall, butts tothe front, upon the rotating carrier mein-Y bers which are continuously in operation.

These puslitlie shear 'into the open gripper and the sheaf'engagi-ng the trip 'arin swings itto; release the latch arm from the lepei.`

Thetension lspring connectedwith the up:

per gripper' vmember snaps said member 'i around lthe shear, the shock being cushioned by a compression spring onthe guidero'd `connected to the lower member andthe supporting bai-l. The movement of thelatch for releasing the gripper member `simulL taneously `releases the clutch dogan'd the crank arni `t5 throiighthe connecting rod 54 swingsthe sheafv carrying bail rearwardly on its pivot in the frame. As the bail swings rearwardly the front tie bar rotates the whole of the sheai carrying mechanismV on. the top ofthe' bail so that'the britt end ido,-

of the shear' swings downwardly while the heed is carriedupwarclly without contact withv4 any part of the machine. Y

Coincidently withtheswinging of thebail the Vlever 89 journalled on `the lower endy of the bail is swung yon its pivot by its con'` n'ection with the crank arm and throtigh 'the rod 88, yoke 87 and link rods86, one* or other of the bevel gears" 78 is moved` iiitj mesh with one ofthe pinions on the con# stantly rotating cross shaft. The crank car? ric'd on the vbevel gear Carries the hook= shaped packer member forwardly while 11,0 machine mo said member. isk moving forwardly the mechanism for operati ng. the sheaf cariy-` ing bail and gripper isarrested by the arm 91engagin'g the clutch dog 52.v 'Iliepacker o member is` swung inwardlyso Vthat the hookedends engage the forward'side of the sheaf and pulli t.out of the gripper vand carry it rearwardlyon to the skids resting it yon its buttand kagainst the sheaf bail.

VImmediately followingthe` removal of the sheaf from .the gripper the stop lng on the gages the rigid spur on'the keeper 38 and',v

' This operationz is yrepeated Vand through the operation ofthe rocking stop bar 84 the packer members operate alternately to vtake the sheaves from the gripper. The `sheaves are packed into position on the skids guided by the shock bailand sidespring guide bars until the pressure 'of the bulk of the sheaves, swings the upwardly to operate the connectingparts which throw the yoke 104 into the rearward pathv of inovekment vof the rod 105, then said rodefccts the dropping of the skidsand the raising ofthe shock bailwiththe rearward Vsweep of the arms 114`to deposit the shock, butt end upon the ground in acompact form, the

` This `action follows the delivery of the overbalancing sheaf to the sheaf receptacle and as the sheaf carrying bail swings rear` wardly with the nextsheaf the rod 105 engages the sleeve 106Y and pulling forwardly upon the link 108. and bar. 109 lifts the skids to their original position, simultaneously throwing the shock bail downwardly ready to receive the next sheaf from the gripper.

` A machine such as described is very positive in its operatiom The absolute timing o f the various motions isobviated bythe arrangement oflost motion devices described anda very light and easily handled mechanism is provided which effectively gathers the sheaves into bundles and deposits them as shocks, butt end upon the ground so that they will stand up effectively under the usual conditions. The machine. is a complete mechanism which may be attached to any standard binder Without change or addition other than la traction connection and an operating shaft connection.
